Issue Description:

Note: If this bug occurs in a modpack, please report this to the modpack author. Otherwise, delete this line and add your description here. If you are using an unreleased version of Ender IO (e.g. for 1.8.9), please don't open an issue for features that have not been announced as "finished" or "working".

What happens:

Trying to configure a fluid tank while next to a fluid input containing fluids causes the entire screen to go light blue.
Putting the tank through the crafting grid to clear configs also clears this error, but it turns up again after configuring it next to a fluid input.
Current workaround: configure the sides before you place it next to the fluid input. Press ESC to leave the blue screen when it occurs.

What you expected to happen:

To be able to see the configuration screen after configuring one side.

Steps to reproduce:

1. Put fluid tank next to another fluid tank that contains fluids
2. Click configure and configure the side connecting to the other tank to pull.
3. Light blue screen
